Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a stable folding boom that is easy to operate. Background Technology

[0002] Mining refers to the process of extracting ore from underground deposits, which is achieved through four steps: deposit development, ore preparation, cutting, and mining. There are many types of mining methods, but commonly, based on ground pressure management methods, they are divided into three main categories: natural support mining, artificial support mining, and caving mining. The underground mining system mainly includes production management, drilling, blasting, ore extraction, ore pass systems, underground crushing, skip hoisting, and hoisting headframe systems.

[0003] A search revealed a mining rock drill boom (publication number: CN219081503U), comprising a telescopic boom. The end of the telescopic boom is fitted with a mounting box via an angle adjustment mechanism. Two sets of slide rails are fixedly mounted on the top of the mounting box, each with a sliding block. A mounting plate is fixed to the sliding block, and the rock drill body is mounted on the top surface of the mounting plate. A second hydraulic cylinder is fixedly mounted inside the mounting box, with its telescopic end located outside the mounting box and equipped with a connector that is fixedly connected to the mounting plate. This utility model utilizes a telescopic boom, enabling the rock drill body to be transported to complex terrain, avoiding the impact of tracked vehicles on drilling operations. Furthermore, the telescopic boom's end allows for fine-tuning of the rock drill body, thereby improving its adaptability to complex terrain.

[0004] Although the above solution uses a telescopic boom, which can transport the rock drill body to more complex terrain and avoid the impact of rock drilling work on areas that tracked vehicles cannot enter, it is difficult to maintain high stability in the working state due to its long boom, and it is prone to swaying caused by the long boom. Therefore, we propose an easy-to-operate stable folding boom. Utility Model Content

[0005] The main purpose of this utility model is to provide an easy-to-operate and stable folding boom. By setting a first adjustment unit and a second adjustment unit, it solves the problem that it is difficult to maintain high stability in the working state due to the long boom and the swaying phenomenon caused by the long boom.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-operate stable folding boom includes a connecting unit, and also includes a first adjustment unit and a second adjustment unit disposed above the connecting unit, wherein the second adjustment unit is located on the side of the first adjustment unit;

[0008] The first adjustment unit includes a U-shaped base mounted on top of the connecting unit, a primary arm movably mounted on top of the U-shaped base, and a first adjustment member disposed between the U-shaped base and the primary arm;

[0009] The second adjustment unit includes a triangular guard plate movably mounted on the side wall of the first-stage arm, a second-stage arm mounted inside the triangular guard plate, and a second adjustment member disposed between the first-stage arm and the second-stage arm.

[0010] Preferably, the connecting unit includes a mounting base and a mounting connection hole formed on the top of the mounting base.

[0011] Preferably, the first adjusting component includes a first pitch cylinder movably mounted at the bottom of the first stage boom, a triangular connecting rod movably mounted on the side wall of the mounting base and movably connected to the telescopic end of the first pitch cylinder, and a first connecting rod with one end movably connected to the first stage boom and the other end movably connected to the triangular connecting rod.

[0012] Preferably, the second adjusting component includes two second connecting rods movably mounted at the bottom of the first-stage boom, a connecting seat mounted on the periphery of the second-stage boom, and a second pitch cylinder movably mounted between the two second connecting rods and whose telescopic end is movably connected to the connecting seat.

[0013] Preferably, the second adjusting member further includes a third link with one end movably connected to the triangular guard plate and the other end movably connected to the second link.

[0014] Preferably, the second adjustment unit further includes a working connection plate installed at the opposite ends of the secondary arm and the primary arm.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, through the provision of a first adjustment unit and a second adjustment unit, when the boom needs adjustment, the extension and retraction of the first pitch cylinder can drive the primary boom to rotate around the U-shaped base via a triangular connecting rod and a first connecting rod, thereby completing the primary adjustment of the boom. The extension and retraction of the second pitch cylinder can also drive the secondary boom to rotate around the primary boom via a connecting seat, thereby completing the secondary adjustment of the boom. When the primary boom rotates around the U-shaped base for adjustment, the first connecting rod strengthens the stable connection between the primary boom and the U-shaped base. When the secondary boom rotates around the primary boom for adjustment, the third connecting rod strengthens the stable connection between the secondary boom and the primary boom. This ensures that the longer boom maintains high stability during operation, reducing swaying caused by the long boom. Attached Figure Description

[0034] When the boom needs to be adjusted, the extension end of the first pitch cylinder 2031 extends and retracts, which drives the first-stage boom 202 to rotate around the U-shaped base 201 via the triangular connecting rod 2032 and the first connecting rod 2033, thereby completing the first-stage adjustment of the boom. The extension end of the second pitch cylinder 3032 extends and retracts, which drives the second-stage boom 302 to rotate around the first-stage boom 202 via the connecting seat 3033, thereby completing the second-stage adjustment of the boom. Example 2

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, an easy-to-operate stable folding boom includes a connecting unit 1, and also includes a first adjusting unit 2 and a second adjusting unit 3 disposed above the connecting unit 1, wherein the second adjusting unit 3 is located on the side of the first adjusting unit 2.
